Applying for solar net metering in Gurgaon involves dual tracking through both the central PM Surya Ghar portal and the local DHBVN / Saral Haryana utility sub-division. Here is how each stage progresses:
Before applying, check your connected load on your latest DHBVN bill. Your planned solar system capacity cannot exceed this sanction load.
Load Enhancement Procedure:
If you want a 5 kW solar plant but currently hold a 3 kW sanction load, an online load enhancement request must be filed on the DHBVN portal with nominal security deposit revision.
The consumer or authorized vendor logs into the PM Surya Ghar National Portal and selects Dakshin Haryana Bijli Vitran Nigam (DHBVN) as the electricity distribution utility.
Saral Haryana Sync:
The registration automatically maps into the Saral Haryana system, generating a unique Application Reference Number (ARN) for real-time tracking at the local subdivision.
The application routes directly to your subdivision SDO (Sub-Divisional Officer) and Junior Engineer (JE) to evaluate local grid capacity.
Transformer Ceiling Review:
DHBVN verifies that solar penetration on your sector’s distribution transformer (DT) has not exceeded the statutory 85% safety threshold. Upon confirmation, formal in-principle TFA is granted.
Once TFA is received, the physical rooftop array is assembled using MNRE ALMM-compliant DCR modules and grid-tied string inverters.
Mandatory Test Dossier:
Voltmen Solar’s licensed supervisors prepare the Work Completion Report, Single Line Diagram (SLD), and earthing resistance test certificate (<5 Ohms) mandatory for DISCOM record.
The approved bi-directional (import-export) meter is delivered to the DHBVN M&T (Metering & Testing) lab in Sector 14 / Kadipur for accuracy bench testing and security sealing.
Field Replacement:
DHBVN staff remove your unidirectional meter and mount the tested bi-directional smart meter.
Solar Billing Activation:
Initial import/export units are signed off by the JE, triggering automatic net-metering energy credits on your bimonthly bill.
Ensure all documents have exact name and address consistency with DHBVN consumer records to avoid subdivision objections:
| Document Name | Purpose & Technical Specifications | Applicant Category | Prepared By |
|---|---|---|---|
| Latest DHBVN Electricity Bill | Must reflect active 10-digit CA / Account Number with zero outstanding overdue arrears. | All Applicants | Consumer |

Standard commercial parameters and technical limits enforced across all DHBVN sub-divisions in South Haryana:
Nearly 35% of self-filed DHBVN net-metering applications face queries, rejection, or multi-month delays due to common avoidable oversights:
Even a slight discrepancy between your DHBVN electricity bill name and your Aadhaar card or bank account will stall both TFA and the PM Surya Ghar subsidy payout.
In older HUDA sectors and builder floors, distribution transformers often approach the 85% loading limit. Applications filed without checking DT margin get held indefinitely.
DHBVN strictly rejects installations utilizing imported or non-ALMM listed inverters lacking BIS-certified anti-islanding protection.
Bi-directional meters must be physically transported and queued at the DHBVN M&T testing laboratory. Delays here add weeks unless tracked daily by field teams.
Voltmen Solar handles 100% of DHBVN subdivision paperwork, Saral portal filings, M&T testing, and JE field inspections so you enjoy seamless rooftop power without bureaucratic stress.
